Has 2 x temperature sensor locations - hi limit and control.
3/4" barbs for tubing connection
*Its extremely important that you ensure water has flooded the heater and is flowing through the plumbing (primed) after installation and after every drain/refill.
Failure of the heater due to 'Dry Running' will likely result if the heater has not properly primed.
This is not a manufacturing defect and therefore not a warranty covered failure.
This heater kit is for replacement of heater models with a second small wire with internal pressure switch, and includes the following:
Inline flow switch and connection tube / clamps
These extra parts are not needed for Hot Spring Spas with heaters that have no separate pressure switch wire, however if fitted to a IQ2020 controller, can be used for additional heater protection by connecting to P34 terminals.
